50-75K for the very basics(including foundation, if there isn’t anything exceptional about the lot. The mls listing has comments about engineering drawings available so you don’t know what that means without looking into it.It looks like it requires a septic system if the health dept will approve it. Electrical should be no big deal since it is in the area.
I think the price for the lot is way too high. This is a pretty eclectic area of expensive homes and dogs where the real value is in the land. There is a lot of commercial stuff nearby. You might want to google earth the area, if you haven’t already.

I have always liked Bonita.The area is being pretty impacted by the growth around it during last 15 years. There is a lot of widening of surface streets and more traffic. Even the 125 is about ready to be opened just to the east. This isn’t so much the quiet little retreat in the concrete jungle that it used to be…It could just get overwhelmed until it almost seems out of place like old parts of Poway, Escondido and PCH.Excuse the ramblings. My sense of nostalgia dislikes the changes.
